APPARATUS FOR ELEVATING ORE FROM MINES.

srncIrIcAirIoN forming part of Letters Patent No. 647,316, dated April 10, 1906.

Application filed November 28, 1899. Serial No. 738,541. (No model.)

T at whom it may concern:

Be it known that we, ROBERT P. MULooK and HARRY WV. WOOD, citizens of the United States, residing at Colfax, in the county of Jasper and State of Iowa, have invented a new and useful Apparatus for Elevating Ore from Mines,of which the following is a specification.

Our object is to save labor and expense in forming connection between a vertical shaft and an inclined lead or lode of ore and to provide means for transferring and elevating loaded cars direct from the mouth of an inclined shaft at the point where it intersects the vertical shaft. Heretofore when a seam of ore extended downward from the surface through adjoining properties that part of the seam or lode nearest the surface could readily v be mined and the ore elevated through the inclined shaft from which the ore was taken; but to mine the ore under an adjoining tract through which the inclined lode extended it has been necessary to sink a vertical shaft some distance below the inclined lode and then extend a horizontal drift to intersect the inclined lode at some distance from the bottom of the vertical shaft and convey the ore first from the inclined lode through the horizontal drift'before elevating it through the vertical shaft.

Our invention consists in the construction, arrangement, and combination of elements and subcombinations in such a manner that the vertical shaft can terminate where it intersects an inclined-lead and the ore taken therefrom carried direct from the inclined shaft in cars and the cars elevated in the vertical shaft and automatically dumped and returned to the inclined shaft from which the ore was taken, as hereinafter-set forth, pointed out in our claims, and illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of our apparatus in position relative to the ground, as required for practical use in a mine, and a car in position, as required before it can descend into the inclined shaft or ascend to the surface through the vertical shaft. Fig. 2 is a view taken from a plane at right angles to Fig. l and shows the relative positions of the inclined track in the inclined shaft, the cage in the vertical shaft, the operative mechanism for retaining the carrier stationary while a car is on the inclined track, and the mechanisms for operating the cage. Fig. 3 is a detail view of that portion of the mechanism adapted to retain the cage in contact with a cam on the wall of the shaft, as required in transferring the car from the inclined shaft to the vertical shaft. Fig. 4.- is an enlarged transverse sectional view of the car, showing a cam on its bottom adapted for releasing the cage from the automatic holder pivotally connected with the uprights of the frame with which the cage is slidingly connected. Fig. 5 is an enlarged view of the base of the cage and means for fastening it at the bottom of the vertical shaft. Fig. 6 is a horizontal sectional View showing the detents connected with the uprights in the shaft and the mechanism for operating them.

The letters A and A designate the parallel uprights of a frame fixed in a vertical shaft to serve as a support and guide for a cage adapted to traverse the vertical shaft and also an inclined shaft that intersects the vertical shaft at its bottom.

A and A are the parallel pieces of a frame fixed to the uprights A and A at the top of the shaft to serve as a platform.

A represents a chute at the end of the platform, into and through which ore is dumped from the car.

A is a rock-shaft in bearings fixed to the platform.

B is a spring-actuated lever fixed to the rock-shaft at the side of the chute A B are spring-actuated detents pivoted in the recesses in the uprightsA and A in such a manner that they will in their normal position project inward to support the cage and alsoin such a manner that they can by suitable mechanism connected with the platform be simultaneously withdrawn from under the cage, as required, to allow the cage to descend.

B are bell-crank levers connected with the detents by means of rods a, and B is a rod pivotally connected with one of the bell-crank levers and the lever B, and an arm B on the other end of the rock-shaft'is connected with the other detent by a rod B in such a manner that both detents can be simultaneously operated by means of the lever B, as required, to withdraw the detents from under the cage to allow the cage to descend after the car is unloaded.

O is the base of the cage in the form of a four-sided frame, and C is an oblong frame (preferably of metal) fixed on the top and center of the base, as shown in Fig. 5.

C are lateral projections on the uprights of the frame 0 adapted to overlie the edges of the uprights A and A as required, to retain the cage in alinement with said uprights and to serve as guides in directing the up and down movements of the cage in the vertical shaft.

' D and D are auxiliary frames fixed to the uprights of the cage to support a roller D journaled thereto. The ends of these frames are also adapted to engage projections D fixed to the wall of the vertical shaft, as shown in Fig. 1, and, as required, to brace the cage when the car traverses the inclined shaft and causes the weight of the car and its load to pull laterally relative to the cage by means of a hoisting rope or cable F, fixed to a bail F, pivotally connected with the car and ex tended over the roller D that has a concaved surfaceto retain the cable in a centralv position relative to the car and cage as they move up and down through the intersecting shafts.

F are stops fixed to the inside faces of the uprights A and A which the baseO of the cage engages and rests upon, and F is a rockshaft journaled to said stops.

F and F are hooks fixed to the rock-shaft and adapted to engage the cross-bar C of the base, as shown in Fig. 5, and, as-required, to retain the cage stationary when the car descends into the inclined shaft.

F is a weight fixed to an arm projecting laterally from the rock-shaft F to normally way in such a manner that a cam K on the bottom of the car will engage the upper end of the lever and operate it, as required, to re lease the cage from the hooks Whenever a car ascends the inclined shaft and enters the cage.

.J and J are track-rails bent double and fixed to the parallel uprights of the cageframe in an inclined posit-ion.

Kis a car mounted on wheels adapted to;

. traverse the doubled track-rails, as required,

inpassing into and outof the inclined shaft. :The upward motion of the car as it enters the cage is arrested bythe bends at the upper ends of the doubled track-rails.

r K isa cam on the bottom of the car that; 1 engages the top of the lever H as required,

torelease the-eage-preparatory to ascending and elevating the loaded car.

K3 is a door hinged to the rear and lower vices.

rear end portions of the sides of the car, re-

strict the movement of the car when it is above the platform at the top of the Vertical shaft by contacting with the edges of the chute A, as required, to retain the car stationary while the door K is opened to dump the contents into the chute to be conveyed to .some receptacle at the other end of the chute.

m are latch-lifting devices pivoted to the outside faces of the chute and adapted in form to serve as cams that will automatically lift the latches m when the car descends and the latches contact with the said lifting de- These devices on" are elbow-shaped andhave inclined planes m' on their ends, as shown in the view adjoining the chute in Fig. 1. 7 When the car moves from the chute, the latches m contact with the under sides of the inclined planes m and lift the devices m, as required, to allow the latches m to pass.

Double track-rails R, fixed in the inclined shaft to connect with the lower ends of the function of each element and subcombination, the practical operation and utility of our invention will be understood by persons fa- .miliar with the artto which it pertains.
